Topic: Drawings for AR-15 Gas Blocks (Read 2569 times)

Just wondering if anyone had any drawing/dimension for the .750 gas block.I was thinking of making a low profile one with switch adjustable gas blowback pressure control. I llike to makes something like Noveske switchblock. I really don't know much about the switchblock, but I can guess. Basically I want to control gas blowback where I can have reduced for suppressed, regular when non suppress, and no blowback.

The set screw is .295 forward from the shoulder(same as the port) and .500" off the center of the barrel hole. Use a 6-32 tap, also tap it with the gas tube in the hole. The gas tube hole is .625 off center from the barrel hole. I forget what all the dims are, I don't have them in front of me.

Isn't a switch block a gas block with a straight tube and different gas holes that you spin the gas tube around?
